' Another object of the invention is to pro-y vide clamping means for the sliding` sajshes of vehicle bodies in which the clamping pressure is equalized, whereby each ofthe cooperating sashes is rigidly secured regardlessV of manufacturing irregularities and variations in size.

V Other objects of thefinvention will kappear i froml the following descri y)tion taken in connection with the drawing, which forms a part of this specification, and in which:

Fig. 2 is a. detail view showing theconstruction of the clamping meanapartially in elevation and partially in section on' the line 2-2 of Fig. 3, and Y .j

' Fig. 3 is a detail view, broken away and partially in section on the line 3-3 of Fig. 2.

In closed motor vehicle bodies ofthe limousine type, it is frequently desired to form the window or glass partition between the drivers con'ipartment and the rear compartment or tonneau, of a pair of horizontal slidable sashes arranged side by side, either or both of which may be. adjustably positioned to regulate the amountof opening'between the compartments." It is very ldesirable that such .sashes be so securedy as not to rattle or' to change their position when the vehicleis in lmotion, and tothis end they are frequently mounted in slides having-a rather tight fit.v

one of the sashes be of slightly different dimensions than the other,.within the range of permissible manufacturing variation, the total clamping efortfwill not be applied extightly clamped.

clusively to the larger of such sashes, thus permitting the smaller of the sashes to re-' main unsecured. y

With reference to the accompanying drawing, at 10 is shown a portion of the body of a motor vehicle of the limousinetype, l'iaving a forward or drivers compartment 11 anda rear Aor tonneau compartmentv 12, separated bythe usual partition 13. They upper part of the partition 1S is formed of a pair of framed sashes, 111 and 15,`each comprising a frame 16, preferablyoffthe familiar pressed metal construction, in which is suitably mounted a glass pane 17. Thesashes 14': and 15 are arranged to slide side by side on af-frame meinber 18 of the partition 13 as is clearly shown in Figs. 2 and 3, and theupper edges of thev sashesare guided in a suitable groove in thel upper frame member of the partition (not show rlhe frame member 18 is provided with suitable trim moulding 19, under the lower edge of'which the fabricv lining `21 of the interior ofthe vehicle body is secured.V l

The frame member 18 is formed at a point i substantially atits centerwith a recess or notch 22, theends of which are closed by metallic plates 23 which may be secured to the frame memberinany suitable'way as byV means of screws24. Each of the plates 28 is drilled to provide alined holes 26, in which a shaft 27' is journaled on reduced. bearing portions 28. Theseportions provide shoul-k 'ders 29 by means of which end motion'of the shaft 27 is prevented. The shaft 27 projects at one end through theplate 28 and is` f provided with a suitable handle81 located within the tonneau portion 12 of the vehicle.

Integral'with or suitablyisecured to the shaft 27 near the central portion thereof is a 'cam 32 which is adapted to exert a clamping pressure upon the sashes on rotationof the shaft 27. In this way the frames 16 of the sashes 14C and 15 are forced upwardly and y By properly positioning the axis of the 'shaft 27 with respect tothe lower faces of the `'frames 16, the upward movement ofthe 'cam can be utilized to directly engage the frames 16 and exert the clamping effort thereagainst. has' been found, however, that the sizesef the sash ffra'me 16 and the th'iclrnessesof themetal ofi which such Vframes are constructed, Vary vvsomewhat within commercial limits, vso that two frames'rwhich are nominally of the same size are not absolutelyl identical. For thisy reason it may happen that the upwa tl pressure exerted by the oai-n on the saeh iii-inne i5, when the Shaft 2T is rotated, ell e erred against thatr eaehfrarne which happens to have the thinker metal or to be slightly the larger, leaving.;` the other unsecured. Y

For this reason the clampingl pressure oit i the earn 32 ie equa-lined between the le rBill e'ule inetien el the 1 and so that both oli' these sashes will be clamped upon rotaii'in 'of the earn, regardless Commercial variation in ilteir tlnueneionsl m n; provided in the io this en l a rece. 4 frame member l@ wbieh communicates with the re-eeen (lireelyabove enel in the rertieal plane et the shaft 2?, ln the ret: is inouiited a floating lever or reulrer 23.4-, han ing upwarfllbY dispos-eil ends or leben 30 and 3"?, zulapteil to e: rage the lower iaee et tl, trainee blt eaelms l-l unil l having' ailownwarclly elf, n tion er lobe 88 adapted to en lever Se which is I thus equalivinr1 the upwardly direetefl elainppressure el the Cani B2 between the sashes Liland l5.
